Three isotopically labeled tri-p-tolylamines, 15N, 15N2D2, and mono-13CH3, have been prepared using zeolite mediated bromination or nitration of toluenes as one of the key steps. The obtained 4-nitrotoluenes were reduced to 4-aminotoluenes, and coupled, v
Side Chain Hydroxylation of Aromatic Compounds by Fungi. Part 4. Influence of the para Substituent on Kinetic Isotope Effects During Benzylic Hydroxylation by Mortierella isabellina

The benzylic hydroxylation of a series of para-substituted toluenes by the fungus Mortierella isabellina has been studied by using CD3, CHD2, and CH2D methyl labelled substrates.Inter- and intramolecular primary and secondary deuterium kinetic isotope effect ratios have been determined: the intermolecular primary effects are maximal with strongly electron-withdrawing para substituents (R = CN and CF3), while the intramolecular primary effects are minimal for R = H but increase in instances where R is electron donating or withdrawing.These results are interpreted in terms of a dependence of the hydroxylation mechanism on the nature of the para substituent.
Asymmetric Synthesis. Mechanism of Asymmetric Catalytic Allylation
Mackenzie, Peter B.,Whelan, John,Bosnich, B.
, p. 2046 - 2054 (2007/10/02)
The mechanism of palladium-assisted asymmetric catalytic allylation has been investigated.It is found that the process involves two primary steps: the oxidative addition of a palladium(0)-phosphine species with an allyl acetate to form diastereomeric ?-al
Determination of the Heats of Formation of the Isomeric Xylylenes by Ion Cyclotron Double-Resonance Spectroscopy
Pollack, Steven K.,Raine, Brian C.,Hehre, Warren J.
, p. 6308 - 6313 (2007/10/02)
Heats of formation of 50 and 53 kcal mol -1 have been measured for p- and o-xylylene by using pulsed-ion cyclotron double-resonance spectroscopy.In addition a lower bound of 76 kcal mol-1 has been obtained for the heat of formation o
